1 The Kerria lacca uses the sticky excretion as a means to stick to the trees on which it lives.

2 You see, the process used to harvest the Kerria lacca excretion is a pretty simple one.

3 The paper introduces current situation about parasite plant species of Laccifer lacca and its stocking, physical nature and the use of shellac as well.

4 Shellac is derived from the excretions of the Kerria lacca insect, most commonly found in the forests of Thailand.

5 Content of amid of host tree has obvious relationship with thickness of raw lac, mortality and fecundity of Kerria lacca.

6 Comparison research trial was conducted on Schleichera oleosa as lac host, including technology of seeding, afforestation, branch utilization and biological characteristics of Kerria lacca.

7 There are obvious linear relationship between individual weight and adult density, between adult density and amount of lac secreted by per Kerria lacca on double logarithmic coordinate axis.

8 In agamous propagation aspect which is rarely studied, technique is given and at last prospects of Kerria lacca host plants are viewed.
